RECORDING-LOCK SYSTEM.

Specification of Letters Patent. Patented Sept. 6, 1921.

-App1'ieat1on filed July 16, 1919. Serial No. 811,120.

T 0 all whom it may con cern Be it known that I, JAMES IV. Baron, a. citizen of the United States, residing at Binghamton, in the county of Broorne and State of New York, haveinvented certain new and useful Improvements in Recording Lock Systems,v of which the following is a full, clear, and exact description.

In the specification which followsI shall describe an invention for which I now seek protection by Letters Patent, which is an improvement 'in what are now generally known as recording locks. These locks are designed to record in permanent form certain information with regard to their use or operation, such as the time at which the lock was operated, either for unlocking or looking the door. to which it is attached, whether it was operated from the outside or the inside, the number of the key and the likie.

At the present time such looks as are used for this purpose are so. designed and constructed that the insertion and turning of a key therein will operate through means of suitable mechanism incorporated. with or forming a part of the lock itself, to send over properly arranged circuits current impulses to a recorder which prints the data corresponding to. such impulses on a paper sheet or strip. I-Ieretofore, however, these locks have been of too complicated a character and have had associated with them mechanism of various kinds which required.

more space than an ordinary lock usually affords, and in general have been required to perform a number of operations which could be more effectively and profitably carried out by the recorder itself. It has been mainly my purpose to simplify their construction and to reduce the number of parts which they involve.

lVith this object in view I have devised the lock herein shown and'claim ed. I have not illustrated herein in detail the recorder.

for use with the system, for the general nature of such instrumentalitles is known,

but I haveshown the essential parts dia Figure 1 is a view in elevation of a com.- plete lock the side of the inclosing casing being removed to exhibit its interior.

Similar referencenumerals indicate corresponding parts in the several figures.

The lock which I prefer to. employ is of the general style and plan of construction of a Yale lock and the key is of'the character usually provided for such looks, with certain modifications hereinafter to be described. Such a lock and key are shown in Fig. 2 of the drawings. The casing 1 is assumed to be securedto a door 2 and to be double, one side being accessible from the outside and the other from the inside of the door. The key 3 is of the usual pattern, but is made somewhat longer than would be neccssary'for the operation of the lock proper,

in orderthat it may operate upon a certain number, preferably three, of tumblers 4 which are provided for controlling circuits to therecorder. I

lVhen the key 3 is inserted into the lock, say from the outside of the'door, it sets'the tumblers or plungers 5 to operate thelock,

while the extended end of the key sets the three additional tumblers 4, raising any one, two or all of the same, as the case may be, and. thereby closing corresponding circuits by the means shown in Figs. 8, 9 and 10.

In these figures the plungers 4 are shown as provided with heads 6 which on being raised separate two and bring together two of three contacts 7 and thus break one or more and complete one, two or more circuits, which remain closed as long as the key is in the lock and whether it is turned or not, following in this respect the action of the key tumblers 5.

As the key may be inserted from either side of the lock, it is necessary for the proper operation to turn the central member 8. for which purpose this part is provided with a transverse perforation and two sliding pins 9 are placed in line therewith which by the insertion of a key are forced into such pcr foration to connect the member 8 with either the right or the left hand part of the lock.

The central member 8 has its ends 1101. lowed out to constitute two sleeves which fit over the tubular key holders 10 so that it is turned only by that lock or key holder which is connected with it by one or the other of the pins 9, and it carries a disk 11 which is formed with a projection 12, Figs. 1 and 7, which engages with a full stroke pawl 13 pivoted at 14 to the lock frame and retracted bya spring 15.

The left hand cylindrical part or sleeve of said member 8 also carries a second disk 16 having two projections 17 extending from diametrically opposite points of its periphery. A third disk 18 secured alongside the others to the member 8 has two diametrically opposite pointed projections 19 extending from its periphery, while a fourth disk 20 is also secured beside disk 18 and this has a single pointed projection 21.

The lock bolt 22 contains two longitudinal slots 23 through which project the guiding pins 24. From the side of disk 11 projects a stud 25 that is adapted to engage with a notch 26, Fig. 7, in the top of the bolt, so that when the key is turned the bolt by such engagement is thrown.

Pivoted at 27 are three levers 28, 29 and 30. A spring 31 is connected with lever 28, a spring 32 with lever 29 and a spring 33 with lever 30, by means of which these levers are actuated. The lever 28 has a turned up end 34 adapted to engage with the second or middle lever 29, and this latter has a hooked end 35, adapted to engage with a stop 36 on the armature 37 of an electromagnet 38. The said lever 29 has also a pointed projection 39 that rides on the periphery of the disk 18.

The upper ends of levers 29 and 30 engage with the turned up end of a lever 40 pivoted at 41 and having an insulating end that is adapted to encounter one of three contacts 42, see Figs. 14 and 15. About the same center 41 also turns a lever 43 with an insulating end that encounters another of the said contacts 44. Both levers 40 and 43 have projections 45 that bear on a cam 46, Fig. 16, on the shaft 47. These parts are so designed that when levers 29 and 30 engage with lever 40 the contacts 42 and 4-4 are in engagement and contact 42 also touches the third contact 48, Fig. 15, with the result to be described.

Surrounding the shaft 47 is an annular insulating disk 49 carrying twenty conducting segments 50 and a circular plate 51, Fig. 7. The shaft carries a contact 52 one end of which sweeps over the circular series of segments 50 and the other over the circular plate 51. The shaft also carries a ratchet wheel 53 adapted to be operated step by step by a driving fork 54 oscillated by the armature 55 of an electro-magnet 56.

Referring now to Fig. 16, when a key is inserted in the lock it raises any one or more of the plungers 4 and closes the circuits controlled thereby, and these circuits remain closed as long as the key is allowed to remain in the lock. The first result of inserting and turning a key through a short are is to bring one of the projections 19 on cam 18 into engagement with the lever 29 and throw the hooked end of that lever over to the right. If magnet 38 is at that moment energized,the hooked end of the lever does not engage with the stop 36 on armature 37 and the lever therefore immediately falls back into a position where one of the projections 17 of the disk 16 engages with a projection on lever 28 which returns to the left with the lever 29. This locks the disks and prevents the key from being turned any farther in the lock. The magnet 38 is what is known as the non-interference magnet and whenever any other lock in the system is being operated and current on the line, this magnetwill be energized so that the lock with which it is associated cannot be operated until after such other lock has been used.

On the other hand, should magnet 38 not be energized, which means that no other lock in the system is being operated, its armature 37 is in its lowermost position, and when the lever 29 is shifted by the key its hooked end engages the stop 36 and is held up thereby, and retains lever 28 in position where it does not interfere with the free movement of the lock.

The operation of the non-interference magnet 38 is controlled by the lever 29 in the following manner. lVhen the said lever is shifted on the initial movement of the key by one of the points 19 011 disk 18 a stop 57 at its upper end engages and brings together two contacts 58 which close a path through the magnet 38 from one side of line circuit 59 to the common return wire 60. Hence if there is any lock being operated on any other part of the circuit which is in multiple with this, the current thereby 50 72 towire 77, when their influence will be caused to flow will also pass through magnet 38 and energize'it. If no such current be flowing the magnet 38 is not afl'ected by the closing of contacts 58.

Assuming that the line conditions are such as to permit the key to be turned, after it has been turned through 90the single projection 21 on the disk20 engages the lever 30 and throws it out of engagement tween the grounded common return wire and one of the line wires 59.

At the recorder a battery 61 is normally grounded at 62, through a circuit controller 64 and a relay magnet 63, hence when contacts 42, 44 and 48 areftogether, the current from battery 61 starting" at ground 62 flows over wire 65 and wire 66 to "contact 48 and thence by' contact 44 and wire 60 back to ground. The relay magnet 63 is thus energized and closes contacts 67 which throw a motor 68 into a power circuit the'wires of which are marked 69.

The motor 68 drives a magneto 70 which produces alternating currents. One terminal of this magneto is grounded at 71 and the other is connected through a circuit controller 74 with a swinging contact arm 75 adapted to beoscillated between two contacts 72 and 76 in such manner by an eccentric or cam 73 on the shaft of the'magneto that positive'impulses of current from the magneto will be sent to line and through the stepping magnet 56 and the negative impulses to a wire 77. The positive current impulses received by magnet 56 cause that magnet through its armature 55 and the pawl 54, to rotate the ratchet wheel 53 and the contact arm 52 step by step over the circular series of contacts 50.

The negative current impulses during the low portion of the wave pass to ground through a contact arm 100, r eciprocated by a double cam 101 on the magneto shaft, but the crests ofthe waves pass through contact exerted; in the manner hereinafter to be described. A condenser 102 is connected with the contact 75 and grounded to modify the impulses in the well understood way. In every operation of a lockyone of the segments 50 which indicatesthe particular key used, will be'rendered live or active dur ing the first part of the, cycle; another whichindicates whether the key was in serted from the inside or .outside will be rendered active during the second part of the cycle; and a third which indicates the particular lockusedv will be permanently connectedin a circuit which is active during the last part of the cycle; so that as the contact 52 sweeps over the segments the proper circuits will be closed to record this data. These operations will be effected by the means to be now described. I have shown three controlled tumblers or plungers 4 andby-means of aplurality of combinations inay be obtained which will connect up with 1I1 3.C131V6C1IC111l3 any one of a plurality of segments to indicate any of eight different keys, and these combinations I are effected in the following manner. By

reference to Fig. 8 it will be seen that one plunger 4 makes one contact and breaks one. The plunger shown in Fig. 9 makes two contacts and breakstwo, while that of Fig.

10 makes four and breaks tour. Bearing this in mind and turning to the diagram Fig. 16

it makes only one contact so that the circuit "is partly madefrom the common return wire 60 to the contact arm '52 and is completed from wire 65 to contact 7*" then through if the first plunger indicated by '4 be raised contact 7" to contact 7 to segment 50 and l to the'contact arm when it reaches that segment.

In a similar manner each plunger carrles the circuit to one of the other segments, and more than these segments may bev connected to the line by simultaneously raising two or more .plungers. For example. suppose plunger 4 and 4 both be raised. Then the cur.- rent will flow to contact 7 but not from there to 7 as the contact there is brokenbv 4", but to 7 where contact has been made by 4b g I Thus it will be seen that each key sets u its combination by which one of the first group of segments corresponding to it is connected to the circuit, so that a current may be caused to flow when the contact 52 reaches that segment, and this current may be utilized in anywell known way to set a type wheel to indicate the number or letter designating such key.

There are two: sets of plungers 4 one being the lettered set shown in the diagram matic view which is efi'ective when the key is inserted from the outside and the other lowerunlettered set being indentical with vices, means are provided for selectively,

connecting certain segments .to determine circuits which. show whether the key is operated to lock or unlock the door and whether it has been inserted from the inside or outside. For this purpose four segments are used. T he means for determining the unlocking or locking status will now be described. The pawl 13, Fig. 1, carries an insulating stud 78 which on the movement of the pawl engages with one or the other of two central spring contacts 80 and 81, and shifts them from their normal engagement with contacts 82 into engagement with con tacts 83. Following now the diagram, Fig. 16, and assuming that the key is inserted and turned to lock the door it moves the contact 80 from contact 82 to contact 83. On the other hand, if the key be turned to unlock the door, then contact 80 will drop onto contact 82, and contact 81 will be forced into engagement with contact 83.

The center contacts 80 and 81 are connected respectively by wires 103 or 102 with the lowermost contacts of the key number combination devices so that either line 103 or 102 is always in circuit with line wire 65. It a key be inserted from the outside and turned the upper lettered combination of contacts will be actuated by the key and the circuit from line to wire 1.03 will be interrupted by one or another of the lettered contacts. However, with the key outside the lower contact devices are in the position shown and a circuit is established from wire 65 through 66, wire 104: through the unlettered lower (inside) contact combination devices to wire 102. Similarly it the key is inserted from the inside wire 102 will be dead and wire 103 will be alive. The foregoing connections establish live circuit conditions for contact 80 and open circuit conditions for contact 81 when the key is operated from the inside and'the opposite circuit conditions when the key is operated from the outside. From the contacts 83-80, 80 82, 8281 and 8183 four wires lead to the four segments 50 which respectively correspond to the following respective door lock conditions: locked outside, unlocked outside, locked inside, unlocked inside. The circuits traced all extent from wire 65.

The main or motor shaft of the recorder carries seven cams which are designated 84, 85, 86, 87, 88, 89 and 90, and these cams have the following functions. Cam .84 is that-which closes the circuit of battery 61 through the relay magnet 63, and is known as the starting relay cam; it is in a position to close this circuit at the beginning of a cycle, and the path for the current impulses which the relay magnet receives through it will be from ground 62 through the con tacts 641, the battery 61, wire 65, wire 66, contacts 1-8 and 44 to the common return wire 60. It will be observed that the motor is-not to be 'started until a key has been inserted and turned in the look, but such. turning completes the circuit which energizes the starting relay, and the cam 84 opens immediately after the motor is started, and

doesnot close again until just before the end of the cycle. 1

The cam 86 is known as the motor control cam. Normally the motor is on open circuit, but by the starting relay the power circuit is closed for a brief period to start it in operation. Immediately after the beginning of the cycle the motor cam closes and stays closed until nearv the end of the cycle, and this maintains the motor in the power circuit through the contacts 91.

The cam 85 is known as the clutch cam. It closes a circuitfrom one of the power circuit wires 69 through contacts 92 and electro-magnet 93 which throws in the clutch (not shown) and thenceto the other power circuit wire through therelay contacts 67.

The cam closesithis circuit before relay 63 is deenergized and breaks it immediately afterward, and the clutch controlled by magnet 93 is of the one cycle variety, that is to say, it remains operative for one revolution after itis once thrown in. The closing of the clutch magnet circuit is timed to take place just after the motor is started in motion.

Cam 87 is the magneto circuit controlling cam, which closes contacts 74 near the beginning of each cycle and opens them near its close.

Cam 88 is thatfihich controls contacts 94 by means of which negative impulses 0t current are sent to line through an electromagnet 95 which sets the type wheel that indicates the pa-rticular key used. These impulses, it will be seen, come from one iole oi the magneto through contact arm 75, the back contact 72, pass through the magnet 95 and the contacts 94 which. by the cam 88, are kept closed only during the first part of the cycle, and from thence flow by wire 65 to one or. another-of the first group of contacts 50, which represent keys.

Cam 89 is that which controls contacts 97, and by them completes the circuit through the magnet 98 that sets the type wheel to indicate whether the key was inserted from the outside or the inside, and whether it was used to lock or to unlock the door. This cam keeps the circuit through magnet 98 clolsed through the second part of the cycle on v. 7

Cam 90 is that which keeps the circuit closed through magnet 99 to the contact 50 that indicates the lock used, and is operative for this purpose during the latter part of each cycle only. i

It will beund erstood that the closing of which are marked 69.

caused to flow will-also pass through magnet 38 and energize it. J If no such current Assuming that the line conditions are such as to permit the key to be turned, after it has been turned'through 90 the single projection 21 on thedisk 20 engages the lever 30' and throws it out of engagement with lever 40 and as at this moment the lever 29 locked up by the stop-36 is also out of engagement with the said lever 40, the latter is released and a circuit is established between contacts 42 and 44: and thus throws the stepping magnet 56 into a circuit between the grounded common return wire 60 and one of the line wires 59.

At the recorder a battery 61 is normally grounded at 62, through a circuit controller 64 and a relay magnet 63, hence when contacts 42, 44 and 48 are together, the current from battery 61 starting at ground 62 flows over wire 65 and wire 66 to contact 48 and thence by contact 44 and wire 60 back to ground. The relay magnet 63 is thus energized and closes contacts 67 which throw a motor 68 into a power circuit the wires of The motor 68 drives 'a magneto 70 which produces alternating currents. One terminal of this magneto is grounded at 71 and the other is connected through a circuit controller 74 with a swinging contact arm 75 adapted to beoscillated between two contacts 72 and 76 in such manner by an eccentric or cam 7 3 on the shaft of the magneto that positive impulses of current from the magnetowill be sent to line and through the stepping magnet 56 and the negative impulses to a wire 77. The positive current impulses received by magnet 56 cause that magnet through its armature 55 and the pawl 54, to rotate the ratchet wheel 53 and the contact arm 52 step by step over the circular series of contacts 50.

The negative current impulses during the low portion of the wave pass to ground through a contact arm 100, reciprocated by a double cam 101 on the magneto shaft, but the crests of the waves pass through contact 72 to wire 77 when their influence will be exerted in the manner hereinafter to be described. A condenser 102 is connected withthe contact 75 and grounded to modify the impulses in-the well understood way.

In every operation ofalock', one of the segments 50 which indicates the particular key used, willbe rendered'live or active dur ing the first part of the c cle; another which indicates whether the key was inserted from the inside or outside will be rendered active during the second part of the cycle; and a third which indicates the particular lock used will be permanently connected in a circuit which is active during the last part of the cycle; so that as the contact 52 sweeps over the segments the proper circuits w-illbe closed to record this data, These operations will be effected by the means to be now described. I have shown three controlled tumblers or plungers 4 and by means of a plurality of combinations-may be obtained which will connect up with an active circuit any one of a plurality of segments to indicate any'of eight different keys, and these combinations are effected in the following manner. By reference'to Fig. 8 it'will be seen that one plunger 4 makes one contact and breaks one. The plunger shown in Fig. 9 makes two contacts and breaks two, while that of 10 makes four and breaks four. Bearing this in mind and turning to the diagram Fig. 16

if the first plunger indicated by 4 be raised itmakes only one contact so that the circuit 'is partly made from the common return wire 60 to the contact arm 52 and is completed from wire 65 to contact 7 the'n through contact 7 to contact 7 tosegment 50 and to the contact arm ment. I I

In a similar manner each plunger carries the circuit to one of the other segments, and

when it reaches that segmore than these segments may be connected to the line by simultaneously raising two or more plungers. For example. suppose plunger 4 and 4 both be raised. Then the currentwill. flow to contact '7 but not from there to 7 as the contact there is broken by contact has been made type wheel to indicate the number or letter designating such key.

,There are two sets of plunnjers 4, one being the lettered set shown in the diagrammatic View which is efi'ectivewhen the key is inserted from'the outside and the other lower unlettered set being indentical with the'firstset and efi'ective when a key is in serted from the inside. Both these sets f contacts are connected in multiple to the line 65 through wire 66 and wire 104.

Either set upon being operated selectivel connects a particular segment 50 to line .65 in accordance with the key number.

- Inaddition to the key number setting devices, means are provided for selectively connecting certain segments to determine circuits which show whether the key is operated to lock or unlock the door and whether it has been inserted from the inside insulating stud 78 which on the movement or" the pawl engages with one or the other of two central spring contacts 80 and 81, and shifts them from their normal engagement with contacts 82 into engagement with contacts 83. Following now the diagram, Fig. 16, and assuming that the key isinserted and turned to lock the door it moves the contact 80 from contact 82 to contact 83. On the other hand, if the key be turned to unlock the door, then contact 80 will drop onto contact 82, and contact 81 will be forced into engagement with contact 83.

The center contacts 80 and 81 are connected respectively by wires-103 or 102 with the lowermost contacts of the key number combination devices so that either line 103 or 102 is always in circuit with line wire 65. If a key be inserted from the outside and turnedthe upper-lettered combination of contacts will be actuated by the key and the circuit from line 65 to wire 103 will be interrupted by one or another of the lettered contacts. However, with the key outside the lower contact devices are in the position shown and a circuit is established from wire 65 through 66, wire 10d through the unlettered lower (inside) contact combination devices to wire 102. Similarly if the key is inserted from the inside wire 102 will be dead and wire 103 will be alive. The I'oregoing connections establish live circuit conditions for contact 80 and open circuit conditions for contact 81 when the key is operated from the inside and the opposite circuit conditions when the key is operated from the outside. From the contacts 83-80, 80 82, 8281 and 81-83 four wires lead to the iour se ments which res ectivel correspond to the following respective door lock conditions: locked outside, unlocked outside, locked inside, unlocked inside. The circuits traced all extent from wire 65.

The main or motor shaft of the recorder carries seven cams which are designated 81, 85, 86, 87, 88, 89 and 90. and these cams have the following functions. Cam 8 1 is that which closes the circuit of battery 61 through the relay magnet 63, and is known as the starting relay cam; it is in a position to close this circuit at the beginning of a cycle, and the path for the current impulses which the relay magnet receives througlji it will be from ground 62 through the contacts 64:, the battery .61, 'wire65, wire 66, contacts 48 and 4a to the common return wire 60. It will be observed that the motor is not to be started until a key has been insorted, and turned in the lock, but such turning completes the circuit which energizes cam. Normally themotor is on open circuit, but by the starting relay the power circuit is closed for a brief period to start it in operation. Immediately after the beginning of the cycle the motor cam closes and stays closed until near the end of the cycle, and this maintains the motor in the power circuit through the contacts 91.

The cam 85 is known as the clutch cam. It'closes a circuit from one of the power circuit wires. 69 through contacts 92 and electro-magnet 93 which throws in the clutch (not shown) and thence to the other power circuit wire throughthe relay contacts 67. The cam 85 closes this circuit before relay 63 is deenergized and breaks it immediately afterward, and the clutch controlled by magnet 93 is of the one cycle variety, that is to say, it remains operative for one revolution after it is once thrown in. The closing of the clutch magnet circuit is timed to take place just after the motor is started in motion.

Cam 87 is themagneto circuit controlling cam, which closes contacts 74 near the beginning of each cycle and opens them near its close.

' Cam 88 is that which controls contacts 94 by means of which negative impulses of current are sent to line through an electromagnet 95- which sets the type wheel that indicates the particulartkey' used. These impulses, it will be seen, come from one pole of the magneto, through contact arm 75, the back contact 72, pass through the magnet 95 and the contacts 94 which. by the cam 88, are kept closed only duringthe first part of the cycle, and from thence flow by wire 65 to one or anotherof the first group of contacts 50, which represent keys.

Cam 89 is that which controls contacts 97, and by them completes the circuit through the magnet 98 that sets the type wheel to indicate-whether the key-was inserted from the outside or. the inside, and whether it was used to lock orto unlock the door. This cam keeps-the circuit through magnet 98 clolsed through the second part of the cycle on v. V a 1 Cam 90, is that which keeps the circuit closed through magnet 99 to the contact 50 that indicates the lock used, and is operative for this purpose during the latter part of each cycle only. a

It wi i be understood that the closing 01 u on the same shaft. The cams have the high points thereof displaced angularly rclatii e to each other. 3

I have now described the chief essential features of the system and given so much of the mode of operation that the improve" ment will be fully understood by'any one been pointed'out that the two contact controlling levers 40 and 4c3have projections 45 that ride on a cam -see Fig. 16-011 the shaft 47. On the first step or movement of the shaft 47 these levers drop from the high point of this cam, with the result that con nection between contacts 44 and 48 is broken, but the circuit isleft complete between contacts 4:2 and 44. If this were not done, all of the magneto impulses would a pass through the magnet 56 and also through the commutator and the key combination circuits which would be undesirable. The lever 43 is not released by levers 29 and 30 although lever 40 is, but said levers 40 and 43 are so designed and arranged that while both are raised and lowered byjthe cam onthe shaft L7 they preserve such relation to each other as to secure the resultabove set forth.

In systems of this kind it is usual to provide for means for recording the time of the operation of a lock, andysuch means may of course be used with this lock, but asthis is something well understood in the art'it is not illustrated or, discussed. Again it is usual to combine withthe lock an autograph recorder, which requires certain modification of the circuits; as far as possible I have omitted in the illustrations such modifications, as these also form a well-known part of theprior art. 4

-The. character of the mechanical details employed in this system is of relatively little importance, provided the functions set forth are capable of being performed. Machines both in this and kindredarts are Well known and in more or less extensive use, and from the prior art any devices may be adopted that will accomplish the results herein described. This applies to all parts of the system with the exception of the lock mechanism which in itself is novel, andfor purposes of the case had to be specially designed. I
